Extended Slide Lock for Glock G43 / G43X / G48 & G-Series Compatible Frames – Cross Armory

Description

The Extended Slide Lock for Glock® G43 / G43X / G48 by Cross Armory is a precision-engineered upgrade designed to make firearm breakdown and maintenance faster, easier, and more efficient—without compromising concealment or holster compatibility.

Featuring an extended but non-protrusive design, this slide lock improves grip angle and finger engagement while maintaining a low-profile footprint that will not interfere with any holster. It complements both factory Glock pistols and ALL G-Series compatible frames functionally and aesthetically.

Manufactured from 4140 ordnance steel and carefully surface-treated for enhanced corrosion resistance, the Cross Armory Extended Slide Lock delivers long-term durability and reliability. Improved geometry minimizes installation time while providing optimal finger response and increased strength over factory components.

Whether you’re performing routine cleaning or detailed maintenance, this extended slide lock significantly simplifies slide removal—making it a practical upgrade for any Glock or Glock-style enthusiast.
